【摘 要】In the operation of cycle hydrogen compressor unit in 1 200 kt/a
hydrogenation cracking plant,leakage have been occurred in gas seal at
high pressure end,which cause the shut-down of the plant.After
dismounting of the seal,it was found that the ring in the first stage seal
had been damaged and there was apparent liquid in there.In this
article,the cause of existence of liquid was analyzed,and prevention
measure was presented,which may be referenced in the field of
compressor maintenance.%辽河石化公司1 200 kt/a柴油加氢改质装置循环氢压缩机组运行过程中,曾发生高压端干气密封一级密封泄漏停车事故.在密封拆检过程中,发现一级密封环损坏,且有明显带液现象.分析了带液原因,并提出了预防措施,在应用维护领域具备较强的参考意义.
